Are all the books of a particular author located altogether in one single library?

No.  It is possible to find several works of the same author in different ULL libraries, and then it is necessary to consult the Main Catalogue (catálogo general) to locate them.

How can I know the amount of books by a particular author a ULL library has?

What you have to do is to click the tab "Subcatálogos disponibles" (available sub-catalogues) and choose the library you are interested in and then browse the field "autor" (author).

Do libraries hold books of all subjects?

There are libraries where you may find books that do not belong to their main study area. For example, the Maths and Physics libraries could hold works related to the field of literature. However, the amount of works does not represent the entire collection of books at your disposal, so please go to a special library that provides further information on the subject you are interested in.

Why are some books inaccessible to users?

Reading rooms house some books that cannot be taken out of the library for conservation reasons, particularly special editions that are no longer available on the market. Because these works are not organized by subjects, their access to the public would be of little help.
